ESA has been studying a number of mission concepts that would benefit from the use of payloads based on Cold Atom Interferometry (CAI).
Once developed, this technology could benefit future Earth gravity gradiometer missions as well as fundamental physics missions. It could also be used to obtain a Bose –Einstein Condensate (BEC) for scientific research. If it progressed into a gravity gradiometer, this could have commercial applications in geophysics, civil engineering and archaeology , to name a few applications.
